Audi has fitted 3 asynchronous motors on their SQ8 and I’m wondering why? I mean, Tesla on their dual-motor, has a synchronous motor for urban use and an asynchronous one for like highwhay and stuff like that. Makes sense I guess. So why would Audi chose 3 asynchronous motor? Efficiency speaking, from what I recall, asynchronous motors are « worst » than synchronous one in a « torque needing » situtation. Is it a way for Audi to say that the SQ8 is to be used on the Autobahn only sort of thing? Thanks for your insights.

I don’t know about Tesla specifics, but most EVs using both synchronous motor and asynchronous(induction) motor don’t work that way. It’s usually PM synchronous motor(PMSM) for the real axle used in most scenarios(urban and highway), and induction motor on the front axle, which is used only when you need extra power or 4WD. The reason is that PMSM is more efficient, so it is used most of the time.
